Was down in these tunnels today, they have not changed since these pictures. The red light with the yellow casing is still sitting there in structure. The old metal buckets in the well room have rusted a lot but still sitting there for a good few years till they are just a pile of dust.
It isn’t open for general access. We are a contractor, the facilities manger mentioned the tunnels awhile ago,I mentioned I would love to have a look so when I was there today he brought the keys with him and we went for a look. Luckily enough they fascinate him as well.
We were also down there as potentially there will be some works carried out on them to put them to use rather than them sitting dormant.
